About this item

The Sun-Mar Spacesaver is specifically designed for places where space is extremely limited. With a width of only 19-1/2 in. and depth of 23 in. this medium capacity electric composting toilet occupies only slightly more floor space than a toilet seat. All Sun-Mar composting toilets incorporate a patented Bio-drum which ensures fast and odorless decomposition. Saves thousands of gallons of water, while recycling waste into soil. The unit is shipped fully assembled. To install, simply plug into a regular 110-Volt outlet and connect the supplied 2 in. vent stack. Seasonal capacity: 3 adults or families of 4. Residential use: 1 adult.
